CARTAGENA, Colombia — ABC News has learned exclusively that the Secret Service officials accused of misconduct in Colombia revealed their identities by boasting at a Cartagena brothel that they worked for President Obama.

Partying at the “Pley Club” Wednesday night, eleven members of the president’s advance team allegedly bragged “we work for Obama” and “we’re here to protect him.”

The officials spent the night throwing back expensive whiskey and enlisting the services of the club’s prostitutes, according to a bouncer at the club and a police source.

Sources tell ABC News several of the men agreed to pay for, and received, services from the “highest category” prostitutes available at the club, who charge upwards of $200.
